The Reddit Saves Glossary
Plain-English definitions of the terms behind saving, organizing, and exporting Reddit content — no fluff, no jargon.
AI Agent
An AI agent is an AI system that doesn't just respond to questions but executes actions to complete tasks — searching, organizing, creating, or deleting things on your behalf. A chatbot tells you how; an agent does it.
Auto-Categorization
Auto-categorization is the use of AI to read a piece of content, understand its meaning, and file it into the right category automatically — no manual tags, folders, or sorting. In Readdit Later, every Reddit post you save is categorized the moment it syncs.
Bookmark Manager
A bookmark manager is an app that stores links you want to keep and adds the organization browsers lack: collections or folders, tags, full-text search, and export. Examples include Raindrop.io for general links and Readdit Later for Reddit saved posts specifically.
Data Portability
Data portability is the ability to export your data from a service in a standard, machine-readable format and take it elsewhere. Under GDPR it's a legal right; in practice, it's the difference between owning your data and renting access to it.
Local-First Software
Local-first software stores your data primarily on your own device — with the cloud as an optional convenience, not the system of record. You keep access, ownership, and privacy even if the service changes or disappears.
Markdown
Markdown is a lightweight plain-text format that expresses structure with simple symbols — # for headings, ** for bold, - for lists. It's the native format of note-taking tools like Obsidian and the safest format for content you want to keep for decades.
Personal Knowledge Management (PKM)
Personal knowledge management (PKM) is the practice of systematically capturing, organizing, and retrieving the information you encounter, so it compounds instead of evaporating. Typical PKM tools include Obsidian, Notion, and Readwise.
Read-It-Later App
A read-it-later app saves web articles into a clean, distraction-free reading queue, often with offline access and highlights. Instapaper and Readwise Reader are the main current options; Pocket, formerly the category leader, was shut down by Mozilla in July 2025.
Reddit Bookmarks
"Reddit bookmarks" usually refers to Reddit's built-in saved posts — the private list created by the save button. It can also mean regular browser bookmarks pointing at Reddit URLs; the two are unrelated systems with different trade-offs.
Reddit Save Limit (1,000 Items)
The Reddit save limit is the platform's cap of 1,000 items returned by any listing — including your saved posts and comments. Older saves still exist in Reddit's database but can no longer be listed by any app or interface.
Reddit Saved Posts
Reddit saved posts are posts and comments you bookmark privately using Reddit's save button. They collect in a single reverse-chronological list at reddit.com/user/YOUR_USERNAME/saved, visible only to you.
Second Brain
A second brain is an external digital system — typically built in tools like Notion or Obsidian — where you store, organize, and retrieve the knowledge you'd otherwise forget. The term was popularized by Tiago Forte's 'Building a Second Brain' methodology.
Semantic Search
Semantic search matches queries to content by meaning rather than exact words. Searching 'negotiating a raise' can surface a post titled 'how I got my salary bumped 20%' — no shared keywords required.
Spaced Repetition
Spaced repetition is a learning technique that re-shows you information at increasing intervals — right before you'd forget it — which dramatically improves long-term retention. Flashcard apps like Anki and reading tools like Readwise are built on it.
